Similar characters of reference indicate like parts throughout the several views.

Referring to Figures l to 5, 8 -to l0 and l-t:

The numerals 20, Q() represent the two upright stiles of a window trame in which two sashes are double hung, 2l the upper horizontal head connecting the upper ends ot these stiles and 22 the horizontal sill connecting the lower ends oit the stiles and provided on the inner part oit its upper side with an outwardly facing rabbet or shoulder 23 and above said shoulder or rabbet with an apron 2l. On the inner side ot each oit the Stiles the saine is provided with an inner stop 25, an intermediate stop or parting strip 26 and an outer stop QT which form the usual inner and outer vertical ruinvays 29 in which is mounted the means whereby the inner lower sash 30 and the upper outer sash 3l are slidably mounted so to permit of opening or closing the same by a vertical rectilinear movement there-oi. Each of these sashes may be of any suitable construction, that :tor example shown in Figures e and 5 consisting ci a wooden l'raine i9 and a glass pane 32 mounted within the sash frame. ln the closed position of the sashes the horizontal meeting rail at the lower end o't' the upper sash and the horizontal meeting rail at the upper end of the lower sash engage with each other, as shown lin Figure l. and the upper end oi the upper sash engages with a horizontal groove formed on the underside or" the traine head between 'the upper horizontal parting strip and the upper outer stop 36 applied to the head7 and the lower end of the lower' sash is provided with a abbot 37 whereby the same nts against the upper surface of the frame sill and the shoulder 23 and apron Qd, thereby forming a weather-tight joint between these members at the places indicated for excluding` rain, wind or snow.

Between the outer edge of the vertical rail ot' each Vot the sashes and the adjacent part of the respective runway of the frame is arranged a mechanism whereby the edge of the respective sash is mounted on the window frame in such manner thatv the saine is capable of sliding vertically thereon and also capable oli being tilted at an angle with reference to the Jtrame for ventilating purposes and also moved into a horizontal position with reference to the trame to afford convenient access to opposite sides of the window glass for cleaning the same from within the building. inasmuch as the several mountings between opposite vertical edges et both sashes and the 'traine are identical. in construction the following description or one will apply to all of them. Secured to the back ot' each runway by means of nails 38 or otherwise are two filling or guide strips 39 of wood or ther suitable material which strips are spaced apart troni each other a considerable distance horizontally so as to form between them a central or intermediate groove l() which is coinparatively wide while the opposite outer sides of these guide strips are spaced apart from the adjacent window stops a comparatively small distance so as to 'form comparatively narrow guide grooves /ll and 4t2 between these guide strips and the respective stops7 as shown in Figures l, 2, 3 and The trent faces of these guide strips or iilling pieces are substantiallyY flush with the iront :taces oli the window stops. Between the 'trout sides of these guide strips and the adjacent vertical outer edge of the respective upright rail of the sash frame is arranged a vertically sliding mounting bar 43 which is preferably constructed ot sheet metal which is substantially equal in length and width to the area of the outer face or side of the respect-ive upright rail. On the upper part of its rear side this mounting or sliding har is provided with a laterally projecting lug i-'l which receives the inner depending stretch of a sash cord or line 45,- the rear stretch of which is arranged behind the adjacent frame stile and provided at its lower end with a sash counter-balancing weight liti while the turn between the inner and outer stretches of this sash cord passes over a sash pulley et? pivotally mounted in an opening in the upper part of the respective sash stile. At its opposite vertical edges the body o't' this sliding or mounting bar is provided with rearwardly proj ecting langcs d8, i9 which are arranged in the narrow guide grooves lll, l2 of the adjacent Yframe stile and are adapted to slide vertically therein and guide the mounting bar during such movement. llt its outer vertical edge the body of each sliding or mounting bar is also provided with a vertical channel 5() which opens inwardly or toward the interior ot the building. ln the lower part or" the bod)7 ot each sliding or mounting bar the same is provided with an upright sash guideway or slot 5l which is preferably formed by bending the metal oit' this body inwardly along opposite vertical edges ot' this slot and there-- by torin guide [langes 52 thereon which project baclwai'dly into the intermediate groove ai() or" the frame runway and are adapted to engage with the opposing sides ot the guide strips 39. On the upper part of the body of the sliding or mounting bar is arranged a brace guideway or slot having a lower part 53 which is of considerable length while its upper end comparatively short and cnlarged compari-al with the lower pariV so lli) thatfthis b ece guidewmyl or slot 'hes Sthe genferzil ppeeranceL ol LkeydiQle, es shown y*for example in Figure L6; At the lower end i of `each 'sliding :or mounting iba-r fthe :Saune .is

While thus turning the sash from its upright position into either an inclined position, as shown in Figure 2, or into a horizontal position, as

shown in Figure 3 the i'ins 6() at the outer vertical edges oi' the weather strips 57 are disengaged from the channels 50. When the sashes are shifted into an inclined position, as shown in Figure 2, the lower outer corners of the weather strips still remain in engagement with the channels so as to maintain a connection between the same in this position. In order to also maintain a connection between the weather strips and the mounting bars when the sash is moved into a horizontal position each of the weather strips is provided at its lower end with a lip 69 which projects downwardly below the adjacent pivot pin 64 and is adapted to engage with the adjacent part of the channel 50, as shown by dotted lines in Figure 3 and by full lines in Figure 14, thereby maintaining the weather strip and the mounting bar in such relation so that upon again closing the sash the outer longitudinal edges or fins 60 of the weather strips will be guided into the remaining parts of the channels 50 so as to properly re-engage the same for forming a weather-tight joint between the respective parts.

It it is desired to wholly remove either of ,the sashes from the frame and the mounting bars this can be done by raising the inner end ot this sash while in its horizontal position sufficiently to bring the coupling pins of its brace bars in line with the upper enlarged ends 54 ot' the brace guideways 53, in which position the enlarged heads 68 of these brace bars may be withdrawn torwardly through the enlargements 54 and thereby wholly detach the brace bars 65 from the mounting bars. To also permit the lower ends of the weather strips 57 to be detached from the channels 50 while the sash is in a horizontal position a. suiliciently loose tit is provided between the pivot pins G4 and the upper parts of the sash guideways 51 to permit these pivot pins 64 to move inwardly an extent sullicient to disengage the lower ends of the weather strips 5r from the channels 50. This preferably accomplished by making the sash guideways 51 somewhat wider than the diameter of the pivot pins 64. To accomplish this purpose itis only .necessary to enlarge the upper part of the guideways 51 but tor convenience in manufacture the same are enlarged throughout ltheir entire height, as shown in Figures f2, 8 and 14. After the brace bars 65 have been detached from the mounting bars 43 and the lower ends of the weather strips 57 have been disengaged from he sash guideways 51, in the manner described, it is now only necessary to tilt the sash in a plane parallel with the face of the window frame or in other words at right angles to the plane in which the same is turned for moving the same into an inclined ventilating position or into a horizontal cleaning position. When thus tilted both pivot pins 64 can be disengaged from the guideways 51 and thereby the sash can be wholly detached 'from the frame :tor convenience in repairing or inspecting the same when this becomes necessary.

A reversal of the operations just described will enable the sash to be again operatively mounted on the mounting bars so that the same can be again swung upwardly into its normal vertical position and then opened and closed more or less in lthe manner in which this is commonly known in double hung windows of this type. By first moving the upper sash downwardly so that its upper end clears the upper intermediate and outer horizontal stops 35 and 36 it is possible to open this sash into an inclined position for Ventilating purposes, as shown in Figure 2 and to swing the same into a horizontal position tor cleaning purposes, as shown in Figure 3, in substantially the same way as this can be done when operating the lower sash in the manner previously described.

Instead of constructing the sliding or mounting bar so that the same has a fiat body as shown in Figures 1 to G and 8 to 10 the same may be stamped out of sheet metal in the form shown in Figures 7 11, 12 and 13. In this last mentioned form of the sliding or mounting bar the same is stamped out of sheet metal so that the body 7 O of the same is provided with a vertical longitudinal channel 71 between its opposite longitudinal edges which opens forwardly. The lower part of Ithis channel is utilized to torni a sash guideway 72 corresponding to the guideway 51 in the construction shown in Figure 6. In this modified form of the sliding or mounting bar the downward movement or the pivot pin 64 in the guideway 79. is limited by means of a block 73 which is secured to the adjacent part of this mounting bar by means of rivets 4 and which also serves as a means of reinforcing or strengthening this end of the bar. The upward movement of the pin 64 in this sash guideway 74 is limited by means of a clip 75 secured in the bottom of the channel 71 by means of rivets 7 6. In this modified construction the lower and upper parts 54 ot' the slot forming the brace guideway are formed in a separate piece of metal 77 which is made of U-shaped form in cross section and secured in the upper part of the channel 71 by brazing or otherwise. On its upper rear part the chan nel portion 71 is provided with a rearwardly projecting web 78 provided with a hole 79 to permit of attaching thereto the ,tront stretch ofrthesash cordr in alinanner similar to that shown inl*1 igure 4;

Nhen this invention is' embodied'in a Window oit the transom type in which the sashl pieces 8O may be permanently securedk by' means Aof nails Si or otherwise to the back of the vertical channel 82 onthe frame stile 2O and the mountingy bar 83 may be permanently secured by means of screws 84 or other suitable means to thelilling strips 80. ln this construction the opposite' vertical edges of the mounting bar are not provided with guide flanges 4l, e2 as in the' construction shown in Figures l to 6 and 8 to l0 inasmuch as no guiding means for the mounting;v

bar are necessary in this case. In this modilied constructionthe vertical sash guide slot has its opposite yvertical edges bounded by rearwardly projccting'iianges 85 which are formed/on the adjacent parts of the body of the mountingibarby foldingor doubling'the metal upon itself', asshown in Figure 15.

ln all essential features however of the constructionshovvnin Figure 15, the same is substantiallylikethat shown inFigures4 l to 6 particularly the manner of mounting the lower end ot the sash on the mounting bars so=as to be capable of slidingverticallythereon and alsoisivingingi in the vertical plane relatively-` thereto; also` the means of con; necting. the upper part` of the sash with the mounting barsV byy means of the pivotediv braces so astohold the fsasheither'in-a par tially opened inclined position` or ina horif zontal full open position, as Well as permitting the sash to be Wholly removed from the mounting. bars ;4 and; also the means'` for producing a Weathertight jointbetiveen the facing strips at` oppesiteedges of the sashy and the channels O-'onthemounting bars. In fact the onlysubstantiall diierence between the constructionof my inventioiivvhen embodied in atverticallyw slidingsash andonel nietalwithout involving anydeparture` from the essence ot' this invention. j

Thismannerof mounting the sashes inthe Window frame not only permits of a better ventilation of the interioroli a room without pern'iitting rain`.v.find and snoiv'to driveinto the san/icas Well as enabling the glass to be cleaned more conveniently Without getting on the outside of the ouilding, but the saine also permits of opening the sashes for ventilating and cleaning purposes by a vertical swinging motion of the saine Without interfering with screens or stormssashes which may be applied to the outer side of the Window iframe. liloreover the construction of these'means of' mounting the sashes in the Window traine are suchthat' the saine will operate elliciently and Withoutbinding or' cramping the parts even though the sashesA may be Warped slightly inasmuch as such warping does not inl'iuence any ofthe mem bers of the mounting mechanism.` Furthermore this mounting is so designed that` the same is practically Weatherproof and' opcrates 'to eliectively prevent the entrance of rain7 Wind or snow intothe building When the sashes are closed and' also produces a tight joint between the sashesA and the frame so that no rattling will occurl when subject to Winds or storms.
